There's been a lot written about clubs having a good first season and then a poor second season after getting promoted.
I can see two reasons for this, firstly the unknown players take established teams by surprise in their first season, so by the second season their players and tactics are worked out.
Alternatively, players get aspirations to earn lots of money elsewhere and the core of the team goes, that coupled with a lot of new players to replace them unsettles the team and means the club doesn't fare as well.
